I really like the metaphors of this poem; they take a little thinking to really appreciate, but you've got some really interesting comparisons going around. The lightning against the wet tree was a good one, particularly as we expected a soaked tree to attract electricity better than a regular tree in a storm like that, however the way you’ve written it seems to suggest the reverse is also true, eg. The form is limp because it’s sodden and therefore less likely to be struck as it’s got less of a sharp point pointing up. I also like the narrative quality about this because that reinforces the metaphors. What I don’t like is the break between the first and second stanzas, because I feel there’s something missing there. It’s just too big of a jump from such a heavy and blocked stanza to a short and direct one. I find that they connect to each other very little like that.
